Re: [Geotools-gt2-users] Is it possible to use the LikeFilter Caseinsensitiv
Tim Englich ha scritto: Hello Jody, our problem ist that the user type his searcvalue wrong. For Example victoria street instead of Victoria Street. We would like to provide that the Features were also found if the user types some characters in the wrong caselevel (upperCase or Lowercase). I know that Oracle provides the function lower (lower(columnName) like 'foo') to provide a comparation which is caseinsensitive. A quick and dirty workaround would be to define a view that has the lower inside, search, get back the fids, and then do a fid query against the original feature type. Messy for sure, but also something you can do without having to fiddle against GeoServer/GeoTools code. Cheers Andrea - This SF.net email is sponsored by: Splunk Inc.

Re: [Geotools-gt2-users] Is it possible to use the LikeFilter Caseinsensitiv
Interesting, could we define a function for geotools called lower and have it map to the SQL lower function?

Re: [Geotools-gt2-users] Is it possible to use the LikeFilter Caseinsensitiv
Hello Jusitin, Hello Jody, for solving my problem in GT 2.3.x I am thinking about a switch which could be set to LikeFilterImpl Class. If the switch is set the String-Values which should be compared will get a toLowerCase() Method call first. Might this be a possible way which could be integrated into the GeoTools SourceCode?

Tim Englich ha scritto: Hello, I am searching for a possibility to use the LikeFilter caseinsensitiv serveral times. I am using the GeoTools 2.3.1 release. I didn't find a possibility yet. Has anyone an idea how I can do this? With the current code you cannot, afaik. You could try to roll your own case insensitive likefilter by subclassing LikeFilterImpl I guess, but then you would also have to alter the sql filter encoders to generate a case insensitive matching sql code (I don't think the sql92 standard allows for this, but some database might), otherwise the sql encoders would keep on encoding the case sensitive version. Alternatively, I think you can create a new filter function, FilterFunction_strToUpperCase, register it in the SPI subystem (look how other filter functions are registered in the text files in META-INF) and then upcase before doing like. Beware that doing so will mean the filter won't be passed anymore to the eventual database, since the datastore would not be able to encode the toUpperCase function. Hope this helps Cheers Andrea - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.
